| <note warning>There may be a bug or at least a glitch on some systems, as ''import -screen'' and ''import -window root'' may show "black boxes" overlaying the window that has been captured, which indicates that some other window(s) are getting on top of it before the capture takes place, even if you don't see it/them!\\ | <note warning>There may be a bug or at least a glitch on some systems, as ''import -screen'' and ''import -window root'' may show "black boxes" overlaying the window that has been captured, which indicates that some other window(s) are getting on top of it before the capture takes place, even if you don't see it/them!\\ |
| I don't know what causes this behaviour, nor have found or really searched for an explanation yet. Nonetheless, it seems that the ''-frame'' switch works better, but it has the same limitations as ''-screen'' (you can't get overlaying windows content). You can also try to minimize all open windows.\\ If it doesn't help, use ''xwd'' for correct captures, or grab your hitchhiking guide and get on google.</note> | I don't know what causes this behaviour, nor have found or really searched for an explanation yet.
